Command Line Interface Guidelines

clig.dev is an open-source guide dedicated to the art of building high-quality command-line tools that balance traditional Unix principles with modern usability. Rather than just listing technical specs, the site provides a thoughtful framework for "human-first" design, covering everything from empathetic error messages and consistent flag naming to the nuances of composability and subcommands. It serves as a go-to manifesto for developers who want to move beyond basic functionality and create CLI programs that are genuinely intuitive, robust, and delightful for other humans to use.
